# xAI Launches Grok 4.5 Coding and Agentic AI Model

> xAI has released Grok 4.5, Elon Musk's first model built specifically for coding and agentic work rather than general chat. Musk has pitched it as an 'Opus-class model, but faster, more token-efficient and lower cost,' priced at $2 per million input tokens and $6 for output. Under the hood sits a new 1.5 trillion parameter foundation the company calls V9, trained heavily on coding, science, engineering, and math, and drawing on datasets from Cursor, the AI coding startup xAI acquired. The distribution strategy is telling. Grok 4.5 arrives inside Grok Build, across all Cursor plans, and in the SpaceXAI console, with European availability expected in mid-July. That puts it directly in front of the developers most likely to judge a coding model on real work. The launch tightens an already crowded field. With OpenAI, Anthropic, and Google all pushing agentic coding assistants, xAI is betting that lower prices and its acquired coding expertise can carve out room. Positioning Grok as a 'truth-seeking' alternative is familiar branding, but the more concrete claim here is a cheaper, coding-native model built to plug straight into the tools developers already use.
